Russian scientists have unveiled a new high-tech robot that they claim can accurately detect and kill humans from over four miles away. Designed for use near volatile borders it is claimed the 'Flight' robot can also detect and shoot aerial threats such as low-flying drones or vehicles from up to six miles away. Using radar, thermal imaging and both colour and black-and-white video cameras, the robot can also discover information about the origins of drones and track their movements before sending the information to Russian military bases. The robot can use multiple long-range grenade launchers and is currently going through operational tests, with chief project engineer Dmitry Perminov saying
